GRATE-SECTION AND FIRE-BED FOR STOVES, FURNACES 80C.

SPECIFICATION forming part of Letters Patent No. 267,910, dated November 21, 1882.

Application filed October 4, 1882. (No model.)

To all whom t may concern:

Be it known that I, WILLIAM MCULAVE., a citizen of the United States, residing at Scranton, in the county of Lackawanna and State of Pennsylvania, have invented a new and useful Improvement in Grate-Sections and Fire-Beds for Stoves, Furnaces, Heaters, and other Fuel- Burning Structures, of which the following is .drawings and thefollowing specification and claims.

In the accompanying drawings, Figure 1 is` a top view ot' my improved fire-bed, the horizontal arms of the grate-sections of which it is formed being in their supporting or normal positions. Fig. 2 is a vertical longitudinal section of Fig. l. Fig. 3 is a similar view to Fig. 1, the horizontal arms of the grate-sections heing in their abnormal positions, as are also the vertical pendent portions of the said sections. Fig. 4 is a vertical longitudinal section of Fig. 3. Fig. 5 is an end of the grate-section, having its angular form slightly changed and its vertical pendent portion grated, in order to lessen the weight of the section, but in all other respects substantially similar to the grate-sections B B', shown in Figs. 1,2, 3, and 4; and

Fig. 6 is a plan view, showing a stationary grated surface'at one end of the grate-frame, which incloses the vibrating grate-sections, the stationary grated surface' being a substitutefor the movable end grate-section, G, shown in Figs. 2 and Aet as well as in Figs. 1 and 3.

A in the drawings may designate the grateframe at the top of the ash-pit section of either a stove, furnace, heater, or other fuel-burning structure 5 but this illustration is best adapted for a stove or furnace, inasmuch as the end portion, A', is made with a concave surface on its under side to allow the end grate-section, C, of the fire-bed to move beneath it in the arc ot' a circle, as shown. Instead of making the underside of the portion A' concave, a rectangular or other form of recess may be provided beyond and above the lower inner edge of said portion A', and thus room for the grate-section C to swing in hack and forward be at'- forded.

The grate-sections B B' are all alike, While the section C is constructed with supportingarms a, which are shorter than the supporting-arms a' on the sections B B. The gratesections B B' are of a form closely resembling a right angle, or more nearlytheletter L when it is inverted and its vertical limb is pendent. The top surfaces of the arms a' may b e made either curved, as shown in Figs. 2 and 4, or straight, as shown in Eig. 5. The length of the arms a. should be nearly equal to the distance between the journals of the respective pairs of sections, so that a nearly continuous grated tire-bed may be `formed when the sections are hung upon their journals c in the grate-frame A and the sections are in their normal positions, as shown in Figsl and 2. The under surfaces of the arms a' may be slightly tapered on their under sid es, either on straight or curved lines, so as to give a sharp end to the arms, and at the same time have the greatest bull: of metal near the angle or bend of the sections.

The pendent vertical or nearly vertical por- `tions azof the sections B, B', and C are made preferably solid, and their front and rear snrfaces may be formed with any desired curvature, as shown in'Figs. 2 and 4, or one surface thereof may be straight up and down, and the other beveled or inclined, as shown in Fig. 5.

At the angle or bend of the sections B, B', and G a portion of the metal is removed between each pair of arms a', so as to form a downwardly-beveled surface, b, and at the same time give a knife-edge formation to the section between the arms and some distance below their upper sides. By this construction the and liability of the arms to warplessened.

-descentof ashes between the arms isfacilitated rEhe portions a? of the sections B, B', and C 95 IOO of the respective portions a2 may be great enough to lap under the respective sections. The sections at their angle or bendk may be rounded or beveled oli", vand at this point they are made with an increased thickness or body of metal, and on each end of each section the short journal c is provided, as shown. The journals c are preferably placed a little forward of and above a diagonal line of the triangular section, so as to about effect a balance between the weight of the pendent vertical portion a2 and the horizontal armsa of the section. This described location of the journals upon which the sections vibrate may be changed so that the journals shall stand on the said diagonal line, as illustrated in Fig.5; but I believe the loca-tion of the journals as shown in Figs. 2 and 4 is far the most advantageous. The ve rtical or nearly vertical portions of the sections,

`are provided near their lower edge, at one end,

with suitable lugs, d, orequivalent means, and

to these lugs a vibrating shaker-bar, d', is connected as illustrated, or in any other proper manner.

In Fig. 5 the portion c2 of the section is shown provided with perforations e. By this construction'the weight of the section will be lessened, while the function of the portion a2 will not be materially interfered with.. In this view the section is shown with a straight uppersurfaced arm, cf, and astraight and bevel-sided portion, a2.

In Fig. 6 the end section, C, of the fire-bed is removed anda stationary grated end portion, E, is applied in its stead, and with this construction all the vibrating grate-sections will be similar to those B B', shown in Figs. 1, 2, 3, and 4, or to the one shown in Fig. 5, inasmuch as it is not necessary to employ a section similar to the one C and have the same turn under the portion A when the space is filled by thev stationary grated surface E, as shown. j

The means for vibrating the grate-sections in one direction or the same direction may.

direction, and if three grate-sections are employed tive cog-wheels would be required-viz., a loose cog between every pair otv cogs of the sections.

In operating with my grated fire-bed the sections can be gently vibrated, so as to shake down the ashes; but when it is necessary to cut out a body of ashes, clinker, or other clogging matter from the superincumbent mass of burning fuel the sections are all moved in Vthe same direction in the arc of a circle, which causes them to assume the position shown in Fig.- 4, in which position the arms d stand nearly vertical with full-open spaces between them for the descent of matter above, while the portions c2 stand horizontal, or nearly so, with the spaces which previously existed between them, as-shown in Fig. 2, nearly or quite closed, as shown in Fig. 4, and in which positions these portions a2 support the mass of fuel until the movement of the sections has been reversed and the arms a are made' to movey back through the mass to theirnormal positions. (Sho\vninl `ig.2.) Thereturnmovement of the sections causes the base portion of the superincumbent mass of matter, consisting of ashes, clinker, cinder, and other dbris, to be separated from the upper portion thereof, relieved from its support, and be discharged into theash-pit.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The vibrating grate-sections B, each comprising a grated portion, a', a pendent portion, a2, and journals, and forming a fire-bed whose sections allvibrate in the same direction, substantially as described. y

2. The grate-sections B B', as constructed, with portions a. and a2 and with journals, and

applied together, whereby the pendent por tion a2 of a section serves alone for closing the space which exists between a pair of sections, substantially as and for the purpose described.

3. rIhe grated firebed formed of sections comprising portions a and a2 and journals, and all moved in the same direction, substantially as and for the purpose described.

4. The combination of an end grate-section, C, formed with arms a', and a pendent portion, a2, the end bar of the ash-pit section, beneath which the section C vibrates, and a section, B. having a form resembling an inverted L, and all moved in the same direction, substantially as and for the purpose described.4
